Abstract: A data storage ecosystem that includes a series of devices of increasing size, designed to look and work together as a family, with at least one of the devices being a data storage device having a first consumer-accessible connector and a second high speed connector. The data storage ecosystem also includes a rack-mounted docking unit having a third high speed interfacing connector configured to couple to the second high speed connector of the data storage device when the data storage device is inserted into the rack-mounted docking unit.

Abstract: A device includes a light splitter configured to receive a source light beam from a light source and split the source light beam into separate light beams, each emitted through an outlet. The device also includes resonators, each of which is optically coupled to at least one of the outlets and is configured to steer at least one of the light beams.

Abstract: A data storage system include a disk drive having a rotating ramp assembly that may be moved between an engaged and disengaged position. The rotating ramp assembly may include a ramp extension that is not disposed in overlapping relation to a data storage disk location in the drive when in the disengaged position. However, in the engaged position, the ramp extension may overhang a portion of the data storage disk location. In turn, the head extension may include a ramp surface that allows a head assembly to move to a head parking surface when the rotating ramp assembly is in the engaged position. IN turn, the rotating ramp assembly may be rotated while maintaining the head assembly on the head parking surface, which may be arcuate and extend about at least a portion of the rotating ramp assembly.

Abstract: An issue facing shared read/write player hard disc drives (HDDs) is when a head-media contact event occurs, any resulting plume of debris caused by the contact event not only affects the magnetic disc currently being read or written, but other magnetic discs within the HDD enclosure. The presently disclosed technology is directed as mitigating the potential consequences of such a head-media contact event. By providing one or more internal access doors within the HDD, a magnetic disc currently being read from or written to may be physically isolated from other magnetic discs within the HDD. As a result, in the event of a head-media contact event, any resulting plume of debris caused by the contact event only affects the magnetic disc currently being read or written. The remaining magnetic discs within the HDD are isolated from the plume of debris.

Abstract: A recording head includes an external cavity laser with an externally mounted part having an active region. The external cavity laser also includes a channel waveguide that delivers light towards a media-facing surface. A near-field transducer functions as a reflector, either alone or in combination with a Bragg grating in the channel waveguide. A reflective back facet of the externally mounted part and the reflector define a resonator of the external cavity laser.

Abstract: A disk drive is operable to determine degradation associated with writing to a disk surface by a head which has written existing data at a first areal density. A second areal density less than the first areal density is determined that remediates the degradation. The disk drive performs subsequent writes to the disk surface at the second areal density, and continues to read the existing data at the first areal density.

Abstract: The technology disclosed herein provides a system for generating a personal unclonable function (PUF) for a user based on a biometric data related to the user. Implementations of the system include a camera to generate a partial image of a user's tongue, a sensor to generate a moisture level in the user's saliva, a PUF generator configured to generate a PUF benchmark of the user based on combination of the partial image of a user's tongue and the moisture level in the user's saliva, and an access control unit configured to control access to one or more user devices based on the PUF benchmark.

Abstract: Systems and methods are disclosed for magnetoresistive asymmetry (MRA) compensation using a digital compensation scheme. In certain embodiments, a method may comprise receiving an analog signal at a continuous-time front end (CTFE) circuit, and performing analog offset compensation to constrain an extremum of the analog signal to adjust a dynamic range based on an input range of an analog-to-digital converter (ADC), rather than to modify the analog signal to have a zero mean. The method may further comprise converting the analog signal to a digital sample sequence via the ADC; performing, via a digital MRA compensation circuit, digital MRA compensation on the digital sample sequence; receiving, via a digital backend (DBE) subsystem, the digital sample sequence prior to digital MRA compensation; and generating, via a DBE, a bit sequence corresponding to the analog signal based on an output of the DBE subsystem and an output of the digital MRA compensation circuit.
